The present invention relates to air conditioning equipment for an air-return area or room by using a damper-diffuser integrated motorized diffuser which has both a damper function to open or interrupt the flow of air and a diffuser function to diffuse air therearound.
BACKGROUND ARTIn current air-conditioning facilities, an area-return type air-conditioning type for each house of houses and multi-use facilities in the related art is divided into a duct return type, a duct return type in which a room space (a hallway and stairs) return type and a room return type are coupled to each other, a ceiling return type, and the like according to a kind of return air. In the area-return type air-conditioning type for each house of houses and multi-use facilities in the related art, an air-conditioning operation for each room is disabled and an operation power cost is excessive. Therefore, as a structure in which the air-conditioning operation for each room is enabled, a ventilation facility type coupled with a multi-air-conditioner which is a refrigerant-carrying type for each room and an area-return type air-conditioning type for each room using a multi-duct have been developed.

Further, in the air-conditioning type, installation costs of refrigerant and dew condensation pipes are high, a repairing cost is excessively generated by a ceiling construction and a replacement construction of the refrigerant pipe when refrigerants leak by deterioration in the refrigerant pipe, a shoddy and fault construction, and the like, and a resident experiences a lot of convenience in repairing as the indoor unit is installed in each area or room throughout the indoor space.
In addition, as a room-unit air-return type air-conditioning type using a multi-duct, an air-conditioning type of houses and multi-use facilities using a packet air-conditioner of an air-return type for each room is shown in

Further, the present invention can be configured to include each of the air supply duct and the discharge duct, such that the present invention can be easily repaired and a repairing cost thereof is low.
Hereinafter, exemplary embodiments of the present invention will be described below in detail with reference to the accompanying drawings.
Air conditioning equipment 500 and 600 of an air-return area or room by using a damper-diffuser integrated motorized diffuser according to exemplary embodiments of the present invention are not shown in
In
A sealing member 14 is preferably installed in the diffuser cone 10 or the diffuser casing 20 to secure airtightness when the diffuser cone 10 and the diffuser casing 20 are closed and a printed circuit board (PCB) 70 for controlling the motor means 60 is also preferably installed in the space part 13 in terms of maintenance. In this case, the PCB 70 and an external power supply are connected to each other through a cable and a connector connected with the cable. Therefore, the PCB 70 and the external power supply may be completely separated from each other easily when the diffuser cone 10 is disassembled. Reference numerals “19 and “22c” represent through-holes of cables 73 and 73a and sealing materials 19a and 74 are preferably installed to maintain airtightness. The diffuser cone body 11 and the diffuser cone cover 12 are fixed by a screw 14a with the sealing member interposed therebetween as in an exemplary embodiment of
The motor means 60 may generally adopt a geared motor using DC power, but is not limited to the configuration. Further, the motor means 60 as a configuration of one example for configuring vertical movement of the diffuser cone 10 may be configured such that a lead screw 62 which rotatably protrudes outside the center of the space part 13 of the diffuser cone body 11 is connected to a motor rotating shaft 61. As such, when the opening rate is controlled by the vertical movement of the diffuser cone 10, a means for preventing rotational movement of the diffuser cone 10 and guiding the diffuser cone 10 to move only vertically is required when the motor means 60 rotates. As one example, the means may include at least one rod-shaped guide means 18 and a fixation supporting member 15 including a through-hole 17 guiding the vertical movement of the guide means 18 and installed in the diffuser casing 20. Further, a fixation nut 65 which engages with the lead screw 62 is fixedly installed in the fixation supporting member 15. In addition, the fixation supporting member 15 may also be installed in an internal casing 21 to be disassembled and assembled. As one example, as shown in the figure, a coupling portion 16 is formed at each end portion of the fixation supporting member 15 in a bent “” shape, a coupling groove having a groove shape into which the coupling portion 16 of the fixation supporting member 15 is inserted is formed at a coupling portion 26 in the internal casing 21, and a through-groove that enables the coupling portion 16 of the fixation supporting member 15 to enter the coupling groove may be installed. By this configuration, when the fixation supporting member 15 is assembled, the coupling portion 16 of the fixation supporting member 15 is inserted through the through-groove and slightly rotates in the coupling groove of the internal casing 21 to be prevented from being separated. When the fixation supporting member 15 is disassembled, the process is reversely performed. As described above, after the fixation supporting member 15 is disassembled and assembled, the diffuser cone cover 12 may be disassembled from and assembled to the diffuser cone body 11.
Further, limit switches 71 and 72 may be installed to limit upward or downward movement of the diffuser cone 10, and particularly, a maximum opening rate adjusting nut 66 is installed together to serve as a stopper and a maximum opening rate of the diffuser cone 10 may be adjusted to prevent unnecessary opening due to adoption to various environments, thereby preventing waste of energy.
In the case where the motorized diffuser according to the exemplary embodiment of the present invention having the above configuration is installed on a ceiling 50 for indoor ventilation or cooling/heating a building, when the motorized diffuser needs to be checked or repaired, the diffuser cone 10 is separated from the diffuser casing 20 and the diffuser cone cover 12 of the diffuser cone 10 is separated from the diffuser cone body 11 to easily check or repair the motor means 60 or the PCB 70. Further, when the adjusting nut 66 needs to be adjusted, the diffuser cone 10 is separated from the diffuser casing 20 to adjust the adjusting nut 66. In particular, when the coupling portions 16 and 26 of the fixation supporting member 15 and the internal casing 21 are configured, the diffuser cone 10 rotates slightly in a decoupling direction and then is lifted up from the coupling groove to be separated through the through-groove, and as a result, the diffuser cone 10 may be separated from the diffuser casing 20. The coupling is achieved in a reverse order to the decoupling. As described above, decoupling and coupling configurations between the diffuser cone 10 and the diffuser casing 20 are not limited to the configurations.
The motorized diffuser according to the present invention having the above configuration and operation may be adopted for indoor ventilation or cooling/heating the building. Since the motor means 60 or the PCB 70 may be disassembled/assembled together with the diffuser cone 10, a check hole is not required and the ceiling may retain an esthetic design. Further, when only the diffuser cone cover 12 is disassembled directly outside, simple maintenance may be achieved more conveniently.
In addition, when the motorized diffuser is not used, the diffuser cone 10 may be closed and displacement of the diffuser cone 10 is easily controlled to control an air volume proportionally as shown in
